Revve API integration services (Canada-Nigeria OpenFinance)

Deliverables checklist

• OpenAPI 3.1 specification covering login, statement, wallet, beneficiary and webhook endpoints
• Protocol and authorization report (token rotation, device binding, anti-abuse signals)
• Runnable reference clients in Python (httpx + pydantic) and Node.js (TypeScript)
• Mock server and contract tests so customer back ends can develop against Revve responses without hitting production
• Compliance appendix mapping endpoints to FINTRAC MSB reporting fields and PIPEDA data-minimization expectations

Quality gates we run before handover

• Round-trip test: send CAD-NGN, capture every state transition, diff against in-app screen
• Idempotency replay on transfer creation and bill-pay endpoints
• Token expiry fuzz: forced 401 on 5%, 50% and 100% of calls to verify refresh logic
• Schema lint and breaking-change check between deliveries (oasdiff)

1. Diaspora payroll reconciliation

A Canadian payroll provider serving Nigerian contractors needs same-day proof of payout. We expose Revve's transfer ledger as GET /v1/transfers with corridor and status filters, then push transfer.settled webhooks into the payroll system. Each event carries the FX leg breakdown so the provider can pin a CAD-equivalent figure to the contractor's payslip.

2. SMB treasury and multi-currency runway

Small businesses moving funds between Canadian operations and Nigerian suppliers can sync Revve wallet balances into a tool like a custom dashboard or an open-source ledger. The wallet balance endpoint returns CAD and NGN positions; a finance lead diffs them against bank balances every morning to flag stuck transfers.

3. KYC/AML enrichment for partners

A licensed MSB partner needs beneficiary-level visibility for periodic re-screening. We surface the saved-recipient catalog (with PII masked at source) and emit beneficiary.added events into a sanctions-screening pipeline. This mirrors FINTRAC's expectation that MSBs maintain ongoing monitoring rather than one-shot onboarding KYC.

4. FX corridor analytics

A research team wants to compare Revve's CAD-NGN customer rate to interbank mid-market over time. The FX rate card endpoint returns mid-rate, customer rate, and spread per refresh window; results are loaded into a time-series store and joined against open data published by central banks.

5. Customer support automation

A help-desk integration listens for transfer.review_held webhooks and auto-creates a Zendesk ticket attached to the in-app conversation. Agents see the redacted payload immediately, cutting the typical "where is my money" first-response time without exposing raw bank account numbers.

Settlement webhook receiver (Python)

from fastapi import FastAPI, Header, HTTPException
import hmac, hashlib, json

app = FastAPI()
SECRET = b"whk_..."

@app.post("/webhooks/revve")
async def on_event(req, x_revve_signature: str = Header(...)):
    body = await req.body()
    expected = hmac.new(SECRET, body, hashlib.sha256).hexdigest()
    if not hmac.compare_digest(expected, x_revve_signature):
        raise HTTPException(401, "bad signature")
    evt = json.loads(body)
    # evt["type"] in {transfer.settled, transfer.review_held, ...}
    enqueue(evt)
    return {"ok": True}

Regulatory framing

Linearsend Inc. operates Revve as a registered Money Services Business with FINTRAC (MSB number C100000083) and as a Payment Service Provider with the Bank of Canada; an FCA registration is in progress for UK reach. Any integration we build inherits these obligations: we keep AML records, never strip identifiers from settled transfer events, and align beneficiary exports with PIPEDA's data-minimization principle.

Privacy controls in our deliverables

• Account numbers and government IDs masked at source; full values only on explicit, logged consent
• Per-call consent receipts (purpose, scope, retention) returned alongside data payloads
• Hash-only logging of phone numbers and emails, with salt rotation
• Configurable retention windows so customers can match Canadian, Nigerian or UK rules
• Sanctions and PEP-list hooks for new beneficiaries before they enter your CRM

Wise

Wise holds multi-currency balances, transaction histories and FX rate data across 40+ currencies. Teams that work with both Wise and Revve typically need a unified statement export so finance can see all corridors in one ledger.

Remitly

Remitly stores per-corridor send/receive ledgers and recipient profiles, particularly strong on Africa and South Asia routes. Integration partners often consolidate Remitly and Revve transfer events for diaspora-payroll dashboards.

WorldRemit

WorldRemit's data model covers cash pickup, mobile-money and bank deposits across African corridors, complementing Revve's app-first flow when an integrator needs broader payout-method coverage.

LemFi

LemFi is positioned for Nigerian and African diaspora users in the UK, US and Canada. Its transfer history overlaps with Revve's, so unified exports are common when serving multi-app diaspora households.

Sendwave

Sendwave specializes in mobile-money payouts (MTN, Airtel) across Africa and processed billions in 2023; combining its event stream with Revve's gives a fuller picture of mobile-money settlement timing.

RemitBee

RemitBee is a Canadian-rooted remittance specialist. Customers who use both RemitBee and Revve often want a single Canada-outbound view across Interac e-Transfer funding sources.

Pesa

Pesa provides multi-currency support and real-time transfers favored by Nigerian users abroad. Operationally, Pesa data joins cleanly to Revve via shared corridor IDs.

NALA

NALA focuses on East and West African remittance with a clean mobile UX. Treasury teams that monitor Revve also pull NALA send-receive events for corridor coverage analysis.

Eversend

Eversend exposes multi-currency wallets and virtual cards; pairing with Revve gives a complete African digital-wallet picture for fintech partners building dashboards.

Afriex

Afriex covers Nigeria, Ghana and Kenya remittance corridors. Integrators frequently group Afriex and Revve when delivering "send to Africa" aggregator products.

About OpenFinance Lab

We are an independent technical service studio specializing in mobile app interface integration and authorized API engineering. The team has shipped protocol analysis, OpenData exports, and OpenFinance integrations for fintech clients across Canada, the UK, Nigeria and Southeast Asia. Engineers come from card networks, MSBs, and platform-security backgrounds, so we pay attention to rate limiting, anti-abuse and key rotation rather than only happy-path coding.

• Source code delivery from $300 — runnable APIs, OpenAPI spec, and full documentation; pay after delivery upon satisfaction
• Pay-per-call billing — access our hosted endpoints and pay only for the calls you make, no upfront cost
• Protocol analysis, custom Python / Node.js / Go SDKs, and test harnesses
• End-to-end pipeline: scoping → analysis → build → validation → compliance hand-off

Engagement workflow

1. Scope confirmation: which Revve flows matter (transfers, wallet, bill-pay, beneficiaries) and which corridors
2. Protocol analysis and API design (2–5 business days, complexity-dependent)
3. Build, mock server, and internal validation (3–8 business days)
4. Documentation, compliance checklist, and customer-side sandbox handover (1–2 business days)
5. Typical first delivery: 5–15 business days; multi-corridor or webhook-heavy stacks may run longer
